Why We Need a Gradient Approach to Word Order Abstract Keywords
Levshina, Namboodiripad, et al. preprint Why we need a gradient approach to word order Abstract This paper argues for a gradient approach to word order, which treats word order preferences, both within and across languages, as a continuous variable. Word order variability should be regarded as a basic assumption, rather than as something exceptional. Although this approach follows naturally from the emergentist usage-based view of language, we argue that it can be beneficial for all frameworks and linguistic domains, including language acquisition, processing, typology, language contact, language evolution and change, variationist linguistics and formal approaches. Gradient approaches have been very fruitful in some domains, such as language processing, but their potential is not fully realized yet. This may be due to practical reasons. We discuss the most pressing methodological challenges in corpus-based and experimental research of word order and propose some solutions and best practices.

A gradient approach means that word order patterns should be treated as a continuous variable. For example, instead of labelling a language as SO (subject-object) or OS (object-subject), we can compute and report the proportion of SO and OS based on behavioural data (corpora and experiments). Similarly, instead of speaking of fixed, flexible, or free word order, we measure the degrees of this variability by using quantitative measures, such as entropy. Instead of simply saying that word order in a language provides a cue for inferring Subject and Object, we will measure the reliability and strength of this cue based on behavioural data.
